A more challenging exercise. Make it a goal if you like. “Show alternatives” below lists easier steps toward it.

This isolation exercise targets the biceps brachii and brachialis by fixing the upper arms on a preacher bench, minimizing momentum and maximizing tension.

Before you start
  • Warm up first with a minute or two of easy walking or marching in place, and cool down the same way after.
  • Wear flat, closed shoes with a good grip, or go barefoot on a non-slip floor if that feels steady to you.
  • Clear the floor around you. Keep a sturdy chair, counter or wall within reach for any move you do standing.
  • Build up slowly. Add repetitions or minutes over weeks, not days. If you take a break, work back up gradually.

Talk with a doctor or physical therapist before you start if you have not been active for some time, if you have a health condition or a worry about exercise, if you have fallen or fear falling, or if a clinician has told you to limit activity.

What you need

A barbell and plates. For squats, presses and anything over your head, a rack or stands with safety catches set at the right height, or a spotter who knows the lift.

How to do it

  1. Sit on a preacher bench with your chest against the pad, gripping a barbell with an underhand, shoulder-width grip.
  2. Position your upper arms firmly against the pad, ensuring your elbows are slightly bent at the start.
  3. Curl the barbell upwards by contracting your biceps, keeping your upper arms stationary on the pad.
  4. Squeeze your biceps at the top of the movement, focusing on peak contraction.
  5. Slowly lower the barbell back to the starting position, controlling the eccentric phase.
  6. Lower until your arms are almost fully extended to get a full stretch in the biceps.

How much

To start: 1 to 2 sets of 8 to 12 slow repetitions, resting 1 to 2 minutes between sets.

As it gets easier: 2 to 3 sets of 6 to 12 repetitions with good form, resting 1 to 3 minutes. Add load or repetitions gradually, no more than about once a week.

How it should feel: The muscles you are working should feel the effort. The last repetitions should be hard but controlled, never shaky or painful.

Tips

  • Maintain constant tension on the biceps throughout the entire range of motion.
  • Avoid lifting your elbows off the pad; this indicates you're using too much weight or momentum.
  • Lower the bar slowly and under control; the stretched bottom position is where the elbows are most exposed.
  • Keep your wrists straight and aligned with your forearms to prevent strain.

Safety

  • Warm up first, and keep your breathing steady. Breathe out on the effort and in as you ease off. Do not hold your breath.
  • Move with control. Do not lock your joints straight at the end of a movement.
  • Choose a version, load and number of repetitions you can finish with good form. The last few should feel hard but not shaky.
  • Begin with the empty bar or very light weight and add weight in small steps.
More safety notes
  • Use collars on the bar, and keep the floor around you clear.
  • Set the safety catches or stand with a spotter so that if you cannot finish a repetition you can put the bar down safely.
  • If you are new to the lift, ask a qualified coach or trainer to check your form.

From the source

  • Avoid lifting your elbows off the pad; this indicates you're using too much weight or momentum.

When to stop

  • Stop and rest if you feel dizzy or lightheaded, sick to your stomach, or unusually short of breath.
  • Stop if you feel sharp, sudden or joint pain. Muscles working hard is expected. Pain is a signal to stop.
  • Stop and sit down if you feel unsteady and cannot settle yourself right away.
  • Call your local emergency number for chest pain or pressure, fainting, or sudden weakness, numbness or trouble speaking.
  • After any of these, do not repeat the exercise until you have talked with a doctor or physical therapist.
  • You cannot complete a repetition with good form. Lower the bar to the catches or the floor and stop.
  • You feel your lower back round or your form break down.
